SMUT-MACHlNE.

SPECIFICATION forming part of Letters Patent No. 276,584, dated May 1, 1883.

Application filed Febrnary21,1883. (No model.)

To all whom it may concern Be it known that I, I. VICTOR HENNIcK, of Buffalo,in the county of Erie and State of New York, have invented certain new and useful Improvements in Smut-Machines; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My present invention has general reference to smut-machines; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claim.

In the drawings already mentioned, which serve to illustrate my said invention more fully, Figure 1 is a broken side elevation of my improved grain-cleaning machine. Fig. 2 is a longitudinal sectional elevation of the same in line as or of Fig. 1. Fig. 3 is a plan, and Fig. 4 a horizontal section in line 3 y of Fig. 2.

Like parts are designated by corresponding letters of reference in all the figures.

A A B in these drawings represent a suitable frame of either cast-iron or wood, the former being preferred on account of cheapness and adaptability. This frame has resting upon the cross-bars B a beam or carrier, 0, for attachment of a spindle-step, T, having a box or journal rendered adjustable by means of adjusting-screws t. This spindle-step supports a vertical shaft, K, provided on its upper end with a pulley, E, by means of which and other obvious mechanism said spindle is rotated at proper speed.

Near the upper end of the frame is a circular disk, D, and in the middle portion thereof an additional disk, L, connected together by a circular cylinder or shell, F, forming the jacket for my smut-machine. In the interior of this jacket F, and at a suitable distance therefrom, is a circular frame, G, the openings G of which are closed by perforated or wirecloth material H, as clearly shown in Fig. 1. In the top disk, D, there is an aperture, (1, from which leads a spout, D, to conduct the grain into the interior of the machine, while another spout or chute, Q, leads the same, when cleaned,

. from the interior of the apparatus.

Upon the vertical shaft K, just below the disk D, is a disk or distribnter, J, upon which the grain falls when escaping from the spout D, and from which it is thrown by centrifugal force. Upon the shaft Kare, furthermore, placed conical or cup-shaped parts N, from which radiate arms n, supporting two or more spiral Wings, 1?, and an inverted cone or deflector, O.

Inthe middle disk, L, are a series of apertures, a, Fig. 4, arranged concentrically around the spindle K, and opening into the space It between the jacket F and the inner perforated cylinder, H, while below the said disk L is still another one, M, so as to. form a chamber, L, serving as a collector for the impurities removed from the grain previous to its being ejected from the apparatus by a fan, S, secured to the shaft K below the disk M and above the fan-casing U. From this fan-casing leads a discharge-duct, R, to convey the dust, &c., to

some suitable place or store-room.

In operation the apparatus is caused to revolve at a suitable speed in any convenient manner, the direction of revolution being such,

I in relation to the spiral wings P, that the grain passing through the spout D upon the disk J is thrown outwardly against the perforated easing El, and its downward movement is counteracted by the. inclination of the said spiral wings. In revolving, these wings throw the grain continually against the perforated cylinder H, at the same time causing a sufficient blastor movement of air to convey all the parti cles of dust and dirt separated from the grain by the beater-like action produced by the spiral wings 1? down the duct or annular space 71., through the apertures a, the collecting-chamber L, and the opening at in the disk M, into the fan-casing U, where the fan S, giving a new impetus to the dust and dirt, forcibly ejects the same from the apparatus through the duct R. While being beaten in the interior of the apparatus the grain gradually descends until finally it is discharged from the interior through the chute Q in a perfectly clean condition. The object of the cup-shaped vessels N is to prevent the grain coming near the center of the annular cleaning-chamber from dropping down, the centrifugal force with which the conical vessels discharge their contents having a tendency to throw the grain IOO the jacket F and perforated shell H, of the shaft K, arms or, spiral wings P, cone-shaped r5 vessels N, conical deflector O, and the deflecting-disk J, the Whole being constructed and combined substantially in the manner as and for the use and purpose specified.

In testimony that I claim the foregoing as 20 my invention I have hereto set myhand in the presence of two subscribing witnesses.

P. V. HENNIOK.
